Evaluates MAX3674 MAX3674 Evaluation Kit The MAX3674 evaluation kit EV kit is a fully assembled and tested demonstration board that simplifies evaluation of the MAX3674 high-performance dual-output network clock synthesizer. The EV kit includes a 16MHz crystal and other hardware components necessary to evaluate all the MAX3674 functions. Software is provided that communicates with the EV kit through a USB port. The software provides an easy way to set operational modes and read/write internal registers. The EV kit is powered by a +3.3V supply and USB port. SMA connectors are used for the reference clock input and LVPECL clock outputs to simplify connection to test equipment. Two LEDs indicate the status of LOCK and USB power.
